Unity Gui lable problem with showing js var using C#

Questions & Answers
1

i get the following errors on my script:
Assets/Scripts/HUD.cs(27,21): error CS1502: The best overloaded method match for UnityEngine.GUI.Label(UnityEngine.Rect, string)' has some invalid arguments AND Assets/Scripts/HUD.cs(27,21): error CS1503: Argument #2’ cannot convert float' expression to type string’

My script HUD.cs contains the following code:

using UnityEngine;
using System.Collections;

public class HUD : MonoBehaviour 
{
	//create a variable to access the JavaScript script
	private Health jsScript; 
	
	void Awake()
	{
		//Get the JavaScript component
		jsScript = this.GetComponent<Health>();//Don't forget to place the 'JS1' file inside the 'Standard Assets' folder
	}
	
	//render text and other GUI elements to the screen
	void OnGUI()
	{
		//render the JS1 'message' variable
		GUI.Label(new Rect(10,10,300,20), jsScript.health);

	}


}

and my JS code is the following:

var MaxHealth=100.0;
var health = MaxHealth;
var regenTime = 20.0;
var regenSpeed = 3.0;

private var timer = 0.0;

function Update(){
if(health <= 0){
die();
}

if(health>MaxHealth){
health=MaxHealth;
}

if(health < MaxHealth){

if(timer < regenTime){
timer+=0.1;
}else{
health+=regenSpeed/10;
}

}else{
timer = 0.0;
}
}




function die(){

}

Your variable health hasn’t been typed. You are using it like a number, but GUI.Label expects a string.

Yes, such problem takes place to be. Second parameter in fact it not string, and GuiContent. That your code earned, change it to the following:

 GUI.Label(new Rect(10,10,300,20), "" + jsScript.health);

On CSharp it helps. It is possible to try and other option:

 GUI.Label(new Rect(10,10,300,20), new GUIContent(jsScript.health));

It seems, it shall help, but precisely isn’t sure (I write everything on CSharp therefore sometimes there are difficulties with the translation into other programming language). And just in case, whether it is necessary to check there is an opportunity to convert float value in string as:

 jsScript.health.ToString();
